Hybrid work model

Job summary

Fluidstack in Austin, TX is seeking an experienced electrical design engineer to own the electrical design of the machine’s power path, including the DC bus, inverter, motor drive, and bearing drives. You will design high-speed hermetic motor drives and ensure safe operation in a rugged data-centre scale system.

The role requires 10+ years in power electronics, proven ability to deliver built converters or drives, drive integration with motors, EMC and safety expertise, and willingness to travel

Qualifications

• 10+ years of experience in power electronics and motor drive design, including high-power converters, high-speed motor drives, and electrical safety for test and production systems.
• You've designed a high-power converter or motor drive that got built, and you were there the first time it drove a real load.
• You've integrated a drive with a motor somebody else designed, and dealt with what the drive then did to the machine and to everything sharing the bus.
• You've chased an EMC, harmonic or bearing-current problem to its actual cause instead of adding a filter and hoping.
• You've written electrical safe work practices and then enforced them on people who found them inconvenient.

Responsibilities

• Own the electrical design of the machine’s power path: the DC bus, the inverter, the motor drive, and the amplifiers driving the magnetic bearings around the rotor.
• Specify and integrate the drive for a high-speed hermetic motor, including the switching, thermal, bearing-current and insulation questions that follow from running a machine fast.
• Design the power and protection scheme for the test benches and the load bank, so a machine can be run to full rating and its output absorbed or regenerated.
• Take the electrical scope through EMC, harmonics and arc flash to an installation that is safe to work on and safe to sign off.
• Own electrical safety in the test cell, including the procedures the technicians and test engineers work to around live buses and stored energy.
